After a long using 4.19.122, i am trying to move for a newer kernel (my xhci greatly improved since), currently it is 5.14.14 and there are noticeable slowdown. For a numbers the Unigine Heaven Benchmark 4.0 (linux OpenGL) was used.

4.19.122:
 FPS: 43.9
 Score: 1105
 Min FPS: 15.2
 Max FPS: 90.7

5.14.14:
 FPS: 31.4
 Score:	790
 Min FPS: 22.4
 Max FPS: 60.1

And there are flickering artifacts visible while benchmarking with newer kernel.

Looks like this bug report are incorrect and the reason are using old amdgpu firmware.
